Abstract: Hot Isostatic Pressing is a proved process for compacting powder metallurgical materials far below their melting point. The aim of this study is the investigation of the transient densification behaviour of powder metallurgical high temperature materials during Hot Isostatic Pressing. The materials investigated, are the nicket-bare superalloy Mimet-700, the titanium alloy Ti6A14V and the titanium silicide TiSi2. An appropriate Instrument (graphite dilatometer) was developed in order to investigate the transient densification kinetics of capsuled powder packings in dependence an HIP processing parameters. The experiments Show, that the main densification occurs during the unsteady stage of a HIP cycle. A simulation modell was developed for the calculation of the transient densification behaviour during a complete HIP cycle. The comparisons between the theoretical and the experimental results allow the determination of materialproperties for power law ereep of Mimet-700 and Ti6A14V. Furthermore, the calculated densification behaviour shows a good agreement with the experimental data for different HIPconditions.
